Close bootstrap modal using typescript in angular 2

Question

I have a button, on the click of which I am opening a bootstrap modal pop-up. The modal pop-up contains some field with a submit button. I want to close the pop-up only when I am done saving the data. I can't use data-dismiss as it will close the pop-up right after user hits the button. Is there a way to close the pop-up through typescript?

expense.component.html

<div id="AddExpense" class="modal fade" role="dialog">
        <div class="modal-dialog">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal">&times;</button>
                    <h4 class="modal-title">Add Expense</h4>
                </div>
                <div class="modal-body">
                    <form id="form" (ngSubmit)="saveExpense();">
                        <div class="form-group">
                            <table class="table table-responsive" style="border:0">
                                <tr *ngFor="#column of columnInputs" style="height:20px;">
                                    <td class="text-right" style="padding-top:10px;border:0">
                                        <h4> {{column.name | case}}: </h4>
                                    </td>
                                    <td class="text-center" style="padding-top:10px;border:0">
                                        <input *ngIf="column.name != 'status'" type="{{column.name == 'created_Date' ? 'date' : 'text'}}" name="{{columns.name}}" required [(ngModel)]="column.value" class="form-control" />
                                        <select class="form-control" *ngIf="column.name == 'status'" [(ngModel)]="column.value" name="{{column.name}}" required>
                                            <option value="status">--Select--</option>
                                            <option value="1">Paid</option>
                                            <option value="2">Unpaid</option>
                                        </select>
                                    </td>
                                </tr>
                            </table>
                        </div>
                        <div class="form-group">
                            <button type="submit" class="btn btn-primary btn-lg"> Add Expense </button>
                        </div>
                    </form>
                </div>
                <div class="modal-footer">
                </div>
            </div>
        </div>
    </div>

Answer 1

you can use the action on close button

<div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" #closeAddExpenseModal>&times;</button>
                <h4 class="modal-title">Add Expense</h4>
            </div>

and in your controller you can add this line after the action you use

this.closeAddExpenseModal.nativeElement.click();

you will need to add this imports to your controller

import { ViewChild, ElementRef} from '@angular/core';

you will need also to define closeAddExpenseModal

@ViewChild('closeAddExpenseModal') closeAddExpenseModal: ElementRef;

Answer 2

With your id="AddExpense", you can close the modal with the below code anywhere in your typescript.

document.getElementById('AddExpense').click(); // where you want to dismiss your modal
